    This version looks fine for me, but I need to give them a test, and
    I will put feedbacks asap. Thanks for your work!

    Still two things:

    1) bitops are always atomic on every arch, right? If yes, then ok.
    2) I hope you could add some documentation to show the relations
    between ip_local_port_range and ip_local_reserved_ports.
